UNITED STATES PATENT OEEICE EDWARD GURNEY, OF TORONTO, CANADA.

STOVE.

SPECIFICATION forming part of Letters Patent No. 585,027, dated .Tune 22, 1897.

Application iled September 3, 1895. Serial No. 561,286. (No model.) i

ized not only to heat the room in which it is placed, but also to heat one or more extra rooms; and it consists, essentially, of constructing the stove with double side walls and bottom and an intake for cold air at the bottom of the stove and hot-air tubes toward the top of the stove extending between the inner walls and connected to the chambers at each side, the chamber at one side being separated and having leading from it hot-air pipes, the stove being otherwise constructed and arranged in detail as hereinaftery more particularly explained. f

Figure l is a perspective view of a woodvstove constructed in accordance with my invention, a portion of the stove being broken away to exhibit the peculiarities of construction. Fig. 2 is a longitudinal section through the-stove. Fig. 3 is a cross-section.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the outer wall of the stove.

B is the inner wall, which is connected directly to the outer wall at the top, so as to leave no space.

O is the intake for cold D is the door.

b is a partition extending from the front to the back of the stove on one side of the intake and at the bottom of the outer and inner walls A and B.

b is a partition extending from the front tothe back of the stove, as shown. The partitions b b thus form the chamber B. I provide openings b2 at thebottom of the chamber and b3 at the top of the chamber B', which air.

` openings are formed in the outer wallA and tapered in form, the small portion of the taper being at the end connected with the chamber A', formed between the walls A and B.

F is a diaphragm extending from the front to the back of the stove and between theinner walls B. The diaphragm F, as shown, is between the top and second row of tubes E.

f are a series of openings extending across the diaphragm F and being formed, preferably, larger at the front and decreasing in size from the front to the back, so that the products of combustion from the iire will be distributed evenly throughout the length of the chamber B2, formed between the diaphragm F and the top ot' the stove. This construction of the diaphragm with openings, as shown, serves to provide for the heating of the pipes more evenly than would be the case it' such diaphragm were not provided, as in that case the major portion of the heat would pass immediately up the smoke-pipe at the back of the top of the stove.

A2 is a chamber formed at the wide end of the hot-air tubes E, opposite to the chamber A and above the chamber B. Suitable thimbles o. at the top of the chamber A2 have connected to them the hot-air pipes H and I, which may be extended to any rooms desired.

The cold air is taken in at C, and the effect of the iire in the stove is to heat such air as it passes upwardly through the chamber A and to further increase the heat of such air as it passes inwardly through the tubes E to the chamber A2, whence it is distributed by the hot-air pipes H and I to the rooms. Such hot-air tubes being tapered, as shown, permit of the rapid expansion and ready circulation of the heated air from the chamber A' to the chamber A2.

v By stoves constructed vas above described it will be seen that I am enabled to utilize the heat, which is sometimes excessive, especially where wood-stoves are used, to heat another apartment or' apartments and at the same time moderate the heat in the room in which the stove is placed.

What I claim as my invention is- 1. In combination with a stove provided with double walls, the combustion-chamber, the intake-chamber leading from below said combustion-chamber, and a series of correspondingly-tapered pipes leading from said IOO intake-chamber across the combustion-chainber to a separate chamber, substantially as described.

2. In combination in a stove, the combustion-chamber, the pipes leading across the upper part thereof and the plate having a series of openings therein, said plate having a portion of said pipes arranged above the saine, substantially as described.

In combination in a stove, the combustion-chamber, the series of rows of horizontal pipes in the upper part of the saine, the horizontal plate interposed between the rows of said pipes, said plate having openings therein corresponding in forni to the contour of said pipes, substantially as described.

4. In combination in a stove, having a donble wall, the space between the two rear Walls being divided into two compartments, the intake-chamber formed by the two front walls the connection between said intake-chamber and the upper rear chamber, the distributingpipes leading from said upper rear chamber, and the lneans for circulating air within the lower rear chamber and discharging the saine into the :room containing,r said stove, substantially as described.
